Feature sprays aspect in the prevention and control of plant diseases, pest control and defoliant of cotton and gradually starts to be applied.But because by aircraft, it is self-possessed and takes
The limitation of dose, insecticide-applying way are mostly the application of low capacity high concentration, and spray particle diameter is smaller, and the unit area amount of spraying is far below ground
The machinery amount of spraying.Simultaneously because cotton planting density is big, the dense plantation growth characteristic of branches and leaves, medical fluid is difficult on cotton leaf
Reach preferable deposition effect, therefore guarantees that medical fluid effective adventitious deposit on cotton leaf is just particularly important.
Wetting characteristics is to influence one of the main factor of droplet deposition effect on plant leaf blade, the wetting of plant leaf blade
Sex expression is blade to the affinity of water, can be measured by the contact angle size formed between drop and blade surface.It connects
Feeler is smaller, and wetability is better, i.e., medical fluid is easier withholding and drawout on plant leaf blade.It is found in previous research,
Drop falls in the contact angle measured on dry blade surface and drop falls in and surveyed on blade surface that liquid pre-wetted
Fixed contact angle is different, and the contact angle that the latter measures wants smaller, shows the latter's wetability more preferably.Meanwhile what is pre-wetted deposits
Spring and landing situation, pesticide droplet when alleviating droplet and plant leaf blade contacts is direct with blade during the deposition process
Effect becomes the effect of pesticide droplet and water, and thus deposition increases, deposition effect is promoted therewith.
There is presently no the correlative study for being administered deposition rule on the cotton to aircraft is seen, more particularly, to cotton leaf

Sampling area, the sampling area include 9 sampled points altogether, and respectively with 1~9 label, the horizontal spacing of each sampled point is 2m, longitudinal
Spacing is 3m.
(4) it pre-wets aircraft X successively individually to carry out with spraying for aircraft Y of application in each plot, carry out four times, four altogether
Plot is independent of each other.Test is first by pre-wetting aircraft X by the course of setting and the amount of pre-wetting of setting to test ground every time
Block carries out uniform sprinkling and pre-wets, and it is that 232PPM (contains soluble solid milligram in 1 liter of water that test, which is sprayed with water water quality value,
Number).To prevent cotton excessively flooded, with reference to Xinjiang flowering and boll-setting period cotton day duty, cotton day is no more than with the maximum amount of pre-wetting and is filled
Irrigating water is foundation, and the amount of pre-wetting in four test plot is respectively 0L/120m2,1.6L/120m2、3.2L/120m2、4.8L/
120m2。
(5) after pre-wetting, application aircraft Y carries out single course line coloring agent to corresponding plot by setting course line and sprays operation,
Set operation height 2m, operating speed 4.0m/s.
(6) application terminates, and after the droplet on cotton leaf is dry, wears disposable glove for each sampled point and meet regulation
The cotton leaf of blade tilt is withdrawn, and is put into hermetic bag label, In Shade preservation.Specifically, in each test plot
Three samples are chosen in sampling area, wherein the leaf sample of 0 °~30 ° blade tilts of Cotton Canopy is chosen in 1~3 sampled point
This, 4~6 sampled points take the leaf sample of 30 °~60 ° blade tilts of Cotton Canopy, 7~9 sampled points take 60 ° of Cotton Canopy~
The leaf sample of 90 ° of blade tilts.
(7) UV755B ultraviolet-visible spectrophotometer (being produced by Shanghai You Ke instrument and meter Co., Ltd) and leaf are utilized
Area measurement instrument (being produced by Yun Nong Science and Technology Co., Ltd. of Zhejiang Top) carries out luminosity to collected cotton leaf subsample
Value obtains and leaf area obtains, and surveys referring to fig. 4 in conjunction with the concentration of the test solution of known concentration and the standard curve of shading value
Obtain standard curve are as follows:
Y=0.0951x-0.0129 (R2=0.9992)
X is concentration mg/L in formula, and y is absorbance.
Further, by the Droplet deposition of the available each processing mode blade of standard curve and leaf area, in turn
Obtain the deposition effect comparing result in four processing plot, the calculation formula of deposition are as follows:
M in formuladThe deposited per area unit amount for being medical fluid on blade, μ L/cm2；VwFor the volume of added eluent, ml；N
For spray liquid concentration, g/L；AsFor cotton leaf area, cm2；MD%The percentage of the setting amount of spraying, % are accounted for for actual measurement deposition；
MvThe amount of spraying, L/hm are set for unit area2。
By the comparison of field trial, the Average droplet deposition for as a result measuring each test plot is respectively 0.046 μ L/
cm2、0.065μL/cm2、0.051μL/cm2、0.058μL/cm2, compared to the plot A without pre-wetting processing, by 1.6L/
120m2、3.2L/120m2、4.8L/120m2The plot B, C, D Droplet deposition for pre-wetting processing in various degree increases separately
39.76%, 9.70%, 24.86%.Blade medicine-feeding liquid Droplet deposition can be dramatically increased by showing to pre-wet.
Simultaneously it is also found that: different leaves inclination angle can also generate different influences to mist droplet deposition, test be provided with 0 °~
30 °, 30 °~60 °, 60 °~90 ° three kinds of blade tilt angular ranges.When not pre-wetted, with the increase of blade tilt,
Droplet deposition is gradually reduced；After being pre-wetted, each angular range Average droplet deposition is increased, and 60 °~90 °
The effect that Droplet deposition in angular range increases is the most obvious.Simultaneously with the increase for the amount of pre-wetting, each angular range is flat
Equal Droplet deposition presentation first increases the variation tendency slowed down afterwards.
Above-mentioned is the preferable embodiment of the present invention, but embodiments of the present invention are not limited by the foregoing content,
His any changes, modifications, substitutions, combinations, simplifications done without departing from the spirit and principles of the present invention, should be
The substitute mode of effect, is included within the scope of the present invention.
